Cells divide for many reasons. For example, when you skin your knee, cells divide to replace old, dead, or damaged cells. ... When organisms grow, it isn't because cells are getting larger. Organisms grow because cells are dividing to produce more and more cells.
Answer:
Explanation:
Cells in an organism go through division all the time. One reason is for growth. As an organism grows, more cells are created. Cells divide instead of grow because there is an optimal size for cell. So it is more efficient to create new cells.
Second reason for cell division is to repair damaged cells. Some cells like skin cells are damaged routinely and cell division is the way to repair and replace damaged cells.
Last reason is for reproduction. All organisms use cell division to reproduce.

Answer:
hardness
Explanation:
Mohs hardness, rough measure of the resistance of a smooth surface to scratching or abrasion, expressed in terms of a scale devised (1812) by the German mineralogist Friedrich Mohs. The Mohs hardness of a mineral is determined by observing whether its surface is scratched by a substance of known or defined hardness.

Explanation:
is the involuntary movement of the muscles that move food through the digestive system
Answer:
Preistalisis
Explanation:
Peristalsis, involuntary movements of the longitudinal and circular muscles, primarily in the digestive tract but occasionally in other hollow tubes of the body, that occur in progressive wavelike contractions. Peristaltic waves occur in the esophagus, stomach, and intestines.
Why does the heart muscle need glucose and oxygen?
To synthesize spores by the process of mitosis
To synthesize ATP using the process of cellular respiration
To synthesize water during the process of transpiration
To synthesize sunlight during the process of photosynthesis

How oxygen moves through an ecosystem
Answer:
Plants and animals use oxygen to respire and return it to the air and water as carbon dioxide (CO2). CO2 is then taken up by algae and terrestrial green plants and converted into carbohydrates during the process of photosynthesis, oxygen being a by-product.

NEED HELP ASAPPPP!!! PLEASEE
Answer:
1. The meaning of a diploid chromosome is a chromosome that has two complete pairs (sets) of chromosomes (from each parent).
2. Muscle cells, bone cells, blood cells, skin cells, and nerve cells are all diploid. (most cells are minus reproductive ones).
3. Haploid chromosomes are chromosomes that only has only a single set of chromosomes that don't have pairs.
4. Reproductive cells are haploid
7. A dog would have 39 pairs of chromosomes (hence the total 78 chromosomes).
8. A dog's reproductive cell would have half of the diploid cell because it is haploid so it would have 39 chromosomes.
10.The only haploid cell out of the 5 options is the ovum/sperm cell because they are the only reproductive cells (and reproductive cells are always haploid unless they combine to make a pair and form a zygote)
Hope this helps! :D

Only plant cells, not animal cells, have chloroplasts. What important process takes place in the chloroplast?
Chloroplasts allow plants to capture the energy of the Sun in energy molecules. This gives energy and nutrients to the plant.
In a population of giraffes, some of them have longer necks than others
Answer:
This is due to evolution
Explanation:
The giraffes with longer necks can reach food more easily than the short neck giraffes so as to reach food in higher trees.
How might long-term climate change affect the behavior of migratory birds that nest in the Arctic tundra?
Answer:
Climate change affects patterns of migration. Global warming also influences the routes of many migratory birds and their annual migration rhythm. A lot of migratory birds change their routes, shorten or completely cancel their journey as a result of changing temperatures.
Explanation: Hope this helps
Answer: well climate change can be many things like if it snows gets colder that means more nesting areas of it gets sunnier or hotter less nesting areas and if that happened then they would have to find different areas to nest at
Explanation:
A skunk living in the northern part of the United States is exposed to extreme cold and food shortages during the long winter months. Based on the climate, what do you predict the skunk's innate response to these environmental factors will be?

What do pesticides, heavy metals, hazardous waste, mining for metals, mining for ores, all have in common?
Answer:
pollution of land and water
Explanation:
Pesticides, heavy metals hazardous waste and mining for metals or ores all cause land pollution.
These contaminate the land kill the useful microbes present in the soil. Moreover, when used excessively these chemical enter in our food chain and through into our body and cause various disease. Minamata disease in japan is one such example cause be mercury contamination.
These cause water pollution too. Chemical waste in water give rise to eutrophication and leaching.

You find an organism growing on a dead log and after careful study, you determine that it is multicellular, heterotrophic, and its cells have cell walls. Given this information, you classify this organism into which kingdom
Answer: This is a plant organism due to it having cell walls but to be specific this is classified as being in the fungi Kingdom such as mushrooms.
Fungus grow on decaying or dead organisms to help break them down Hope this helps ^_^
Answer:
It is in the plant kingdom :) :)
Para que se utiliza el termómetro
Para medir la temperatura de una manera más exacta se utiliza un termómetro. Un termómetro es el instrumento que se usa para medir la temperatura del aire. Los termómetros más comunes son tubos de vidrio huecos. En la parte inferior del tubo se encuentra la ampolleta que contiene un líquido como alcohol o mercurio.
What "gem" is formed as a result of the Carbon Cycle
Answer: Diamonds Form from Fluids in the Mantle That Migrate Due to Plate Tectonics. Diamond is a metasomatic mineral that forms during migration of carbon-bearing fluids, which means that it forms from fluids and melts that move through the mantle.
Explanation:
A track athlete throws a 2kg discus into a field with a velocity of 21m/s. What is the momentum of the discus?
Answer:
Given :
Momentum of disc = 42 kg m/s
Velocity of disc = 21 m/s
To Find :
Mass of the disc.
Solution :
❖ Momentum is defined as the product of mass and it's velocity..
Mathematically, p = m × v
p denotes momentum
m denotes mass
v denoted velocity
➛ It is a vector quantity having both magnitude as well as direction.
➛ It can be positive, negative or zero.
➛ SI unit : kg m/s or N s
By substituting the given values;
➙ p = m × v
➙ 42 = m × 21
➙ m = 42/21
➙ m = 2 kg
∴ Mass of the object is 2 kg.

As per newton's second law of motion, force is measured as the rate of change of linear momentum.

ver a long period of time, flower shapes and color variation have changed as a direct response to attract more pollinators, such as bees and hummingbirds. This is an example of --
Predation
Competition
Parasitism
Commensalism
Answer:
This is an example of parasitism
Ver a long period of time, flower shapes and color variation have changed as a direct response to attract more pollinators, such as bees and hummingbirds. This is an example of Predation. Thus, option A is correct.
What are predators?A predator is a creature that eats all or a portion of the body of its victim, which may be alive or recently deceased. Predators are distinguished from decomposers, such as fungus and bacteria, which break down the remaining remnants of dead species, by the phrase "living or recently killed."
We can confidently classify a lion as a predator if we witness it devouring a zebra. However, the zebra is included in the wide definition as well! Prey for a predator can include both plants and fungi as well as living things.
Additionally, a predator is not required to kill its victim. Instead, it can just remove a part of the prey's body and leave it alive, like a grazing cow or a bloodsucking mosquito. Herbivory is the term for a predator-prey situation in which an animal or insect eats a plant; herbi- stands for plant, and -vory implies eating.
Therefore the correct option is B.
